Scientists projected that global emissions of carbon dioxide will hit another record high in 2018, highlighting the urgency of international climate talks underway in Poland.
The estimated 2-3% rise in year-on-year emissions worldwide would translate to 37.1 billion metric tons of carbon dioxide released in 2018 — equivalent to 1,175 metric tons of carbon dioxide spewed into the air every second. Global CO₂ emissions came to 36.2 billion metric tons last year.
